first i'd kick the guys ass and punch him then kick him in the nuts........then i'd hit him with anything i find.......when he passes out......i'd call the police and 911 then help the girl and do everything i can to help.......

I would most likely casually ask the lady if she needed assistance. Who knows? It could be just some skit or some kind of twisted fetish or something and making yourself look silly isn't on my priority list.

The altruism of this group is outstanding. Very few people are, however, immune to the Bystander Effect. But given the fact you are alone and you saw someone getting rape, it is actually natural to help them. I probably would help them out too. And because I almost always carry my Leatherman around with me, I at least have a small weapon to attack and defend my self with. And if i don't have that, I think a tackle and a chock hold will do.

Here is what I would do. I would call the cops on my cell phone. Then I would get close enough to take a picture of him. Then I would yell out at a distance saying I called the cops. I would wait to see what he would do. If he tries to run I will try my hardest to chase after him. I really hate rape crimes. I would probably go psycho and tear him a new one honestly.

Eurgh i hate all these internet heroes its obvious most f them would do nothing, I'm not saying I would be the hero either because I don't know what I would do until I'm unlucky enough to be in this situation.
